WE DON’T RECOMMEND USING SCREWS WHEN MOUNTING DIRECTLY ON THE TREE!
You can see in the pictures below where the screws compressed the springs and drove the tag all the way down to the tree. This defeats the purpose of leaving room for the tree to grow. Even if they had left room for the springs to expand, the screws are larger than the holes, so the tag cannot slide on the screw. If the screws are smaller than the holes, if it is put in at the slightest angle, the tag could get caught up on the screw’s threads, not allowing it to slide. National Band & Tag is not responsible for ruined tags due to incorrect mounting.
Use a wood post set in concrete and then use screws or nails to mount the tag onto the post. Or use a metal post and use wire to tie the tag around the post. (NB&T does not supply posts).
#4 Hang the Tags
You can use zip ties or wire to hang the tags off a branch.
